WINDOW-SASH;

SPECIFICATION forming part of Letters 'Patent No. 621,953, dated March 28, 1899.

Application filed ovember22,1898. Serial No. 697.131. (No model.)

To all whom t may concern:

Be it known that I, CLINTON D. TABoR, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Window-sashes, of which the following is a specification.

This invention relates to that class of window-sashes which can be raised and lowered in the usual manner for opening and closing the window and which can also be reversed, so that either side of the sash is accessible from the inside of the building for cleaning or repairing the same, so as to avoid the danger attending cleaning and repairing windows from the outside of the building.

The object of my invention is to produce a window-sash of this character which is simple and durable in construction and reliable in operation and which can be conveniently detached from and attached to its supports.

In the accompanying drawings, consisting of two sheets, Figure 1 is an inside elevation, partly in section, of a window provided with myiinproved sashes, showing the upper sash slightly tilted. Fig. 2 is a vertical transverse section of the same in line 2 2, Fig. l. Fig. 3 is a fragmentary vertical section, on an enlarged scale, of the lower sash in line 3 3, Fig. 2, showing the same in its normal operative position. Fig. t is a perspective view of one of the guide-bar sockets which receives one of the pivots of the sash. Fig. 5 is a fragmentary edge View of one of the guide-bars and the socket attached thereto and showing the pivot seated therein in section. Fig. 6 is a fragmentary edge View of one of the stiles of the window-sash and its pivot. Fig. 7 is a fragmentary horizontal section in line 7 7, Fig. 3, showing the sash in its normal operative position. Fig. 3 is a similar View showing the position of the parts when the sash is turned slightly on its pivot. are fragmentary horizontal sections inlines 9 9 and l0 10, Fig. 3, respectively. Fig. 11 is a fragmentary vertical section in line 1l 1l, Fig. 3. Fig. 12 is a fragmentary vertical section similar to Fig. 3, showing one of the guidebars held in a retracted position against the side jamb of the frame. Fig. 13 is a horizon- Fig. 14 is Figs. 9 and lO an end View of one of the side-jamb thimbles which receives one of the guide-bar catches.

. 4Like letters of reference refer to like parts in the several figures.

The window-frame may be of any usual and well-known construction and consists, essentially, of two vertical pulley or side jalnbs A Aa head-jamb B, connecting the upper ends of the side jambs, anda sill C, connecting the lower ends of the side j ambs. The inner side of each side jamb is provided with the usual inner stop D, intermediate stop D', and outer stop D2, which extend vertically from the sill to the head-j amb and form an inner guideway d and an outer guideway d between these stops.

E E' represent the upper and lower sashes, which abut with their check-rails e e' and engage with their top and bottom rails c2 e3 against the head-jamb and sill, respectively, when the sashes are in their normal position, the same as in the sashes now commonly used. The width of each sash, or, in other words, the distance between the outer edges e4 of 4the Stiles e5 of each sash, is less than the distance between the stops D D D2 on one side jamb of the frame and the corresponding stops on the side jamb on the opposite side of the frame, which permits the sash to pass freely between the two sets of stops.

F represents vertical guide-bars whereby the sashes are guided in their vertical movements and upon which the sashes may be swung in a vertical plane for turning either side of the sashes inwardly. One of these bars is arranged in each of the guideways and bears with its inner longitudinal edge against the opposing edge of the adjacent sash-stile, the pair of guide-bars on the opposite sides of the lower sash being arranged in the inner guideways d and the pair of guide-bars on opposite sides of the upper sash being arranged in the outer guideways d. The guide-bars on opposite sides of each sash are of the same length and flush with the top and bottom thereof and are connected with counterbalancing-weights g by cords g', passing around pulleys g2 on the side jambs. One side of each stile, preferably the outer side f, is of such width that it practically lls the space between the adjacent outer edge of the sash-stile and the back IOO of the adjacent guideway, while theopposite 'or inner side f thereof is of a width less than said space, which permits the narrow portion of the guide-bar to rock to a limited extent in a horizontal plane toward and from the outer edge of the adjacent sash-stile. The guide -bar during this rocking movement turns with its cornerf2 at the juncture of the outer side and outer edge thereof in the adjacent corner of the guideway as a pivot. Each of the guide-bars is provided on its inner edge near its inner side with a longitudiiial rib or tongue h, which engages with a corresponding groove ZL in the opposing outer edge of the adjacent sash-stile.

Each of the sashes is connected with the central portions of its stiles to the central portions of its guide-bars by horizontal couplingbolts I I, so that the sash and its bars move up and down together and the sash can turn. in a vertical plane on the guide-bars. Each of these bolts is guided in a frame fitted in a recess in the outer edge of a sash-stile and consists of a face-plate j, through which the middle portion of the bolt passes, andl a yoke j, through which the inner portion of the bolt passes. The outer edge of the coupling-bolt is provided with a head j?, having a conical or convex back side.

The coupling-bolt is constantly drawn inwardly by a spring Zr?, surrounding the bolt and bearing with its ends against the inner side of the face-plate, and a washer Zt, which in turn bears against a pin 7a2 on the bolt.

L L represent sockets which receive the headed ends of the coupling-bolts and which are arranged on theinner edges of the guidebars. Each of these sockets consists of a face-plate Z, secured over a recess Z in the inner edge of the guide-bar and provided with a slot consisting of a vertical portion Z2 and a horizontal portion Z3, which extends laterally from the upper end of the vertical portion and opens inwardly through the guideway, For the purpose of connecting the sash with its guide-bars the heads of the couplingbolts are iirst slipped into horizontal portion Z3 of the socket-slots, this operation being facilitated bylimiting the inward movement of each bolt, so that in its innermost position its head projects beyond the outer edge of the sash-stile. The inward movement of the coupling-bolt is preferably limited by engaging the washer Zt' or the pin k2 with the yoke j'. After the coupling-bolts have been slipped into the horizontal portion of the socket-slots the bolts are pressed downward into the vertical portion of the slots until the bolts engage with the lower ends thereof. As the bolts move downwardly in the sockets the head of each bolt engages with its back side against inclines m m, arranged on the faceplate on opposite sides of the vertical portion of the slot, whereby the bolt is moved toward the guide-bar and the spring 7s is strained, thereby causing thev guide-bar and sash to be firmlydrawn together, so as to prevent leakage and rattling at the joints. In the lowermost position of the coupling-bolts the heads thereof engage with vertical bearing-faces m m on opposite sides of the socket-slot, which causes the spring to draw the head of the bolt squarely against the socket and prevents the tension of the spring from displacing the bolt in the socket, which would be liable to happen if the head of the bolt rested against an incline when in its operative position.

Then the sash is connected with the guidebars by the coupling-bolts and the sashis in its normal vertical position ,the springs 7s serve to retain the sash in this position by yieldingly holding the ribs ZL of the guide-bars in engagement with the grooves of the sashstiles, thereby causing the sash to rise and fall with the guide-bars when opening and closing the window. When it is desired to reverse the sash for cleaning the pane or for other purposes, it is turned on the couplingbolts as a pivot, whereby the upper and lower ends are swung in opposite directions. This movement of the sash causes the curved or inclined sides of its grooves to engage with the corresponding sides of the ribs on the guide-bars on the principle of a wedge and turn or deflect the same in a horizontal plane, as shown in Fig. 8, so that the ribs clear the grooves and permit the sash to be swung freely into any desired position. Upon returning the sash to its normal vertical position the guide-bars are instantly drawn horizontally against the stiles and their ribs are again engaged with the grooves in the stiles. The wedge action of the sash against the guide-bars is preferably prod need by making the ribs of rounded or convex form and the groove in the stile of corresponding'form; but, if desired, the rib on the guide-bar and its cooperating groove in the sash-stile may be of tapering or conical form. The corner f2, on which the guide-bar turns, preferably has the form of a narrow rib or ilange, as shown in the drawings, which permits that side of the guide-bar to iit snugly between the sash-stile and the back of the guideway, thereby preventing leakage between the guide-bar, sash, and frame, and it also forms a small contactsurface between the guide-bar and the guideway, thereby reducing the friction and wear removing the lower sash the latter is raised, together with its guidebars,sufcient to clear the lower stop n on the sill, and for the same IOO IOS

IIO

purpose the upper sash is lowered with its guide-bars, so as to clear the upper stops a on the head-jamb.

For the purpose of permitting the sashes to be easily and conveniently detached from and attached to the guide-bars each of the latter is held stationary d urin g the operation of detaching and attaching the sashes by a retaining device, which is constructed as follows:

O represents a depending catch, which is arranged in an outwardly-opening recess o' in the lower end of a guide-bar. rThis catch is provided at its lower end with an inclined hook o2, which extends upwardly and laterally toward the adjacent guide-bar, and its upper end is provided with a vertical slot 03, which receivesatransverse pin o4 on the sashstile.

P represents a cylindrical thimble arranged inthe back of each guideway near the lower end thereof and provided on its upper side with a transverse shoulder or lip p, having an inclined inner side p', which extends from its lower end upwardly andA laterally away from the adjacent guide-bar. In the lowermost or closed position of the lower sash its catches engage with the sill and are raised in the sash-Stiles, as shown in Fig. 3, this movement of each catch being permitted by the slotted connection of the catch with the stile. The catches of the upper sash when in its lowermost position are raised in the stiles thereof by engagement with the sill in the same manner'as the catches of the lower sash. In the elevated position of the sashes the catches thereof drop until the upper ends of the slots therein engage with the supporting-pins o4, in which position of the catches their hooked lower ends project below the' stilcs. Vhen it is desired to detach thelower sash from its guide-bars, the latter, together with the lower sash, are raised until they clear the bottom stop u, and the catches thereof depend below the stiles and stand opposite the catch-thimbles in the guideways cl. Thecatches are now swung laterally out of the recesses o', so that they stand at an angle to the guide-bars and their hooks are engagedl with the inclined lips of the thimbles, as represented in Fig. l2, whereby the guide-bars are held against further upward movement. Upon now moving the sash upwardly andinwardly its coupling-bolts are disengaged from the bolt-sockets.

Vhen the sash is disengaged from the guide-bars, the upward pull upon the latter by the counterbalancing-weights causes the inner or narrow portion of the guide-bars to be drawn horizontally backward toward the guideways by the catches, as represented in Figs. l2 and 13, whereby the Vguide-bars are held in a retracted position, so that their ribs clear the path of the sash and permit the latter to be conveniently inserted between the guide-bars. The backward or outward movement of each guide-bar is produced by the lowering the sash and its guide-bars after the sash and bars are coupled the catches disengage themselves automatically from the thimbles by gravity, aided, if necessary, bythe inclined hooks of the catches engaging with the lower edges of the thimbles, whereby the catches are forced inwardly into the recesses of the sash. The catches are retained in these recesses with their hooks clear of the thimbles by gravity, so that in the normal position of these parts the sash can be freely raised and lowered.

The upper sash is preferably lowered in its guideways when it is desired to remove the same from its guide-bars so as to be within convenient reach, and for this purpose the thimbles for the reception of its guide-bar catches are arranged near the lower ends of the outer guideways CZ, as shown in Fig. 2.

The detachable connection between the sash and its guide-bars is particularly desirable when the full opening of the window is required-for instance, when moving large furniture through the window.

The removability of the sashes from the guide-bars is also very desirable when the window is provided on its outer side with a4 screen which extends the full height of the window. When such screen is used, the sashes cannot be reversed for cleaning, because the screen is too close to the sash, and the latter therefore has to be removed from the guide-bars in order to afford proper access to both sides of its pane. of the sashes isv permitted Without removing the guide-'bars from the frame and disconnecting the same from the sash cords and Weights.
